Knee-jerk attacks on Educators (teachers and administrators) are cliche these days. It is sad, people claim to value education... yet they offer no respect to the people actually working to provide education. People will turn on a dime on educators for anything (including this).
What is wrong with more then one valedictorian? The article you posted explains the reason that educators decide to do this. Did you even read past the headline, or was this a impulsive response based on your preconceived ideas? Have you even thought about the issues involved outside (outside of your initial reaction)?
I worked as a public school teacher dealing with the challenge of providing a good education to a large, diverse student body. In my district, the top 20% of kids did pretty well. There were lots of resources available to them including advanced classes and programs.
One goal we discussed quite a bit was how to provide for the middle group (we called them the "mid-kids"). These were the kids that did alright, but not spectacularly... in general they did not have the natural ability that the top group had, nor the curiosity and motivation. (They tended to be from poorer families, but that is another issue). We wanted to provide the best education, resource and opportunities for these kids as well.
When educators ask about things like honor roll, and valedictorian... it is not some macho perspective of toughness. Real educators think very carefully about the message they are sending to students. The answers that they come up with will vary based on the needs of their communities and students.
The question is what will best meet the needs of the students and the goals of the school.
A knee-jerk answer based on a fear of women's genitals is not what is needed.
